svnlite barfing when updating from repo

[Baho Utot]

when I am update my ports repo like this

svnlite co "https://svn.freebsd.org/ports/head" "/usr/src/ports"

svn: E155009: Failed to run the WC DB work queue associated with 
'/usr/home/FreeBSD/source/ports/head/net-im/mastodon/files', work item 
132774 (file-remove net-im/mastodon/files/patch-bin_yarn)
svn: E000013: Can't remove file 
'/usr/home/FreeBSD/source/ports/head/net-im/mastodon/files/patch-bin_yarn': 
Permission denied

What causes this?
I am updating the repo as a regular user and not root and the directory 
has the proper perms.

I am getting this after I update a repo ( i do this once a month ) and 
it was fine last moth and now I get multiple failures.  After:
rm -rf /usr/home/FreeBSD/source/ports/head/net-im/mastodon/files/; 
svnlite cleanup;
svnlite co "https://svn.freebsd.org/ports/head" "/usr/src/ports"

It will run until it finds another perm problem so I have to 
shampoo,rinse,repeat until the local repo is finally updated
